A number of male sterile stocks in barley homozygous for various high lysine genes have been developed. We are or will be using these stocks to facilitate hand and natural field crossing in our high lysine genetics and breeding program. These stocks can be particularly useful in producing known hybrid seed in quantity when allele testing unknown genes.
Presented in Table 1 are the stocks developed. These will be available in small lots upon request after May of this year. Lysine data is presented in Table 1 as evidence of the presence of high lysine in the stocks and to aid other investigators in judging the potential of these stocks in their own programs.
Table 1 High Lysine - Male Sterile Stocks Available
A Bomi, Riso Mutant No. 1508, chromosome 7 male sterile stock has not been developed. We tried with msg 19 but failed to combine the two characters. Linkage between the two characters is suspected (see this issue of BGN). Crosses have been made this winter between No. 1508 and other chromosome 7 male sterile genes (msg 16, 18 and Z) to further the linkage study and for development of a male sterile stock.
